What grants are available in Ireland?
SEAI is the main grant provider for home energy upgrades, and support is usually spread across different upgrade types rather than one single payment.
Most homeowners combine multiple home energy upgrades based on their home, upgrade path, and expected overall savings.
- Insulation grants
- Heat pump grants
- Solar PV grants
- Windows and doors grants (limited or conditional)
Grants by upgrade type
Heat pump grants
Typical support is often around EUR6,500, while heat pump cost in Ireland still depends on eligibility and scheme rules.
Insulation grants
Grants can apply across attic, wall, and floor insulation depending on the measure.
Solar panel grants
Solar PV support can be part of a wider retrofit plan once core upgrades are clear.
Windows and doors grants
Support can be limited and conditional, so it is important to check current criteria.
Find your likely grants based on your home
Use the planner to estimate your likely grants based on your home type, BER starting point, and upgrade path.
Who is eligible for retrofit grants?
- Owner-occupied homes are typically eligible for many grant types.
- Some landlords may be eligible depending on the scheme.
- A BER assessment is often needed where minimum BER improvement is required, especially for heat pump routes.
- Technical requirements still need to be met before support is approved.
How the grant process works
- Assess your home (BER and technical readiness), often starting with a BER assessment.
- Choose upgrades in a practical order using a retrofit plan and what to upgrade first approach.
- Apply through SEAI and/or your contractor route.
- Complete the upgrade works.
- Grant support is paid after completion.
Important: grants usually come after the work is completed, so upfront budget is still needed.
Common mistakes with grants
- Choosing upgrades based only on grant size.
- Installing a heat pump before improving insulation.
- Underestimating additional costs not covered by grants.
- Assuming grants cover the full project cost.
- Not planning upgrades in the right order.
How grants fit into your upgrade plan
Grants work best when they follow a fabric-first approach, so your home is prepared before bigger system changes.
A practical sequence is usually insulation, then ventilation, then heating, then solar.
For sequencing guidance, read what to upgrade first. For budget planning, compare the cost after grants. You can also consider whether the right sequence may increase house value.
